This has been one of, if not the worst natural disasters I remember in my lifetime. My mom was asking me questions about it today and asking what type of bombs we dropped on them after Pearl Harbor. I was so pleased to see her so alert and inquisitive. She was pointing out how at one time we (the US) were one time enemies and now we are friends and allies. I didn't know the answer to her question though. She wanted to know if they were hydrogen or atomic, or one of each. She lived through that time and was telling me things that happened back then.
This level of destruction from nature is a little hard to comprehend. I hope they get any radiation threat contained. I heard that some sailors were contaminated on the Ronald Reagan.
